Question

Determine the range of the following graph:

Answer 1

Answer as an inequality:    $\boldsymbol{2 \le y \le 7}$

Answer in interval notation: [2, 7]

==========================================================

Explanation:

The range is the set of all possible y outputs of a function.

The lowest point occurs when y = 2

The highest point occurs when y = 7

The range is the set of every y value between 2 and 7, including the endpoints.

The range as an inequality is $2 \le y \le 7$

It is equivalent to [2, 7] in interval notation. The square brackets include each endpoint.
